Abstract

A process is provided comprising contacting and reacting the compound CF 3 CF 2 CHXCl, wherein X is H or Cl, or the compound CF 3 CF═CXCl, wherein X is H or Cl, with hydrogen in the presence of a catalyst consisting essentially of Cu, Ru, Cu—Pd, Ni—Cu, and Ni—Pd, to obtain as a result thereof reaction product comprising hydrofluoropropenes or intermediates convertible to said hydrofluoropropenes, notably CF 3 CF═CH 2 and CF 3 CH═CHF.

Claims (8)
